Support for USB-CDC
Version 1.1 of the Tock bootloader adds:
- Support for the USB-CDC stack so the bootloader will work on boards with USB headers directly attached to the MCU (i.e. no FTDI chip).
- New command to set the jump address.
- Only supports 512 byte pages over-the-wire.
- New traits to separate out jump and entry code.
- Checks to not overwrite the bootloader itself.
